The boxing people guiding Vargas didn't do anything wrong. They led him to world titles and big money paydays. That is exactly what you are supposed to do with a talented fighter. Unfortunately, when you have a bunch of money, you need to invest it and that puts you into contact with people that make the characters in boxing pale in comparison...the real seedy characters are in the financial world, not the boxing gym. Vargas didn't sue his trainer or his manager, just his financial guy.
